INVENTOR May-Bram ATTORNEY Patented Mar. 3, 1931 ARTHUR BROWN, OF LAKECITY, IOWA WORK-HOLDING DEVICE Original application filed May 11, 1929,Serial No. 362,376. Divided and this application filed May 19,

1930. Serial No. 453,781.

vide a. device for supporting rods, pipes, fiat bars or boards andholding the same against movement while operating thereon.

Other objects will in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and ends, my invention.consists in the novel features of construction and in the combination,connection and arrangement of parts,

hereinafter more fully described, and then pointed out in the appendedclaim-s.

In the drawings:

Figure 1 is a top plan View of the device, the chain or flexible elementbeing omitted.

Figure 2 is a side elevation of the same, the chain or flexible elementbeing omitted.

Figure 3 is a transverse vertical section on the line 3-3 of Figure 2,the chain or flexible element being shown as used for the purpose 3-0 ofholding down a bar in the crotch formed by the members 10.

Figure is an enlarged detail cross section- :11 view of a portion of thedevice, showing how the same may be used for holding aboard or flat bar.

Figure 5 is a detail side elevation of the device showing the same inuse for holding a board as in Figure l, on which board a vise or otherworking implement may be mounted.

In the drawing in which like numerals of reference indicate like partsin all of the figures, it will be seen that the device comprises a frameconsisting of end transverse bars 11, and an intermediate transverse bar3 connected by crossed bars 2, the same being secured at proper placesby rivets 4 as 1ndicated. Mounted on the base are standards composed offiat bars 5 having foot portions 6 riveted to the base. There arethreesets of bars 5, the two end ones and an intermediate set. The barsor a set converge and then extend vertically upward as at 7 where theyagain diverge at 10 to constitute the saddle members. Secured to one endstandard and to the intermediate standard at one side is a combinedbrace andstop bar 8, the same being riveted or otherwise secured inplace as at 9, the purpose of which will presently appear. p

The diverging arms 10 of the standardbars have holes 11 through whichmay be passed pins 12 on which an article-to-be-supported' of a catchplate 24 that is secured to one of the standards composed of the bars 5.

- A spring 26 may be secured to the lever 22 and another spring 27secured to the ear 21, these springs having hook ends to which the chainor flexible element 28 may be connected.

7 29 represents a rod, bar, pipe or other article held on the saddles 10by the chain 28 passing over the same and being placed under tension bypressing down on the lever 22 and causing the catch tooth 23 tointerlock with one of the notches 25 of the catch plate 24.

l/Vhen it is desired to'secure a board or flat bar on the supportas whenit is desired to mount a vise 31 for example, the cross pins 12 areplaced in the proper openings 11 and the board 30 laid thereon. Thechain 28 is then passed over the board as indicated in Figures 4 and 5and the lever is pressed down tightly and latched in itstensioned'position, thereby securely holding the board 30 on thesupport.

This application is a division ofmy application filed May 11, 1929,Serial No. 362,376v

From the foregoing description, taken in connection with theaccompanying drawings, it is thought'the.construction and uses of myinvention will be clear to those skilled in the art to which it relates,and I desire it understood that slight changes in the details ofconstruction may be made without departing from the scope of theinvention and the appended claims.

WVhat I claim is: LA Work holding device comprising a fraine composed ofa base and end' standards which includes legs and diverging saddle arms,a lever fulcrnined atone; end toone leg of a standard, a rack platesecured to the other leg of the same standard tocooperate with saidlever, a spring, one end 01": which is anchored to said frameadjacentthebase, a flexible element, one end of WhlClTlSSGCLlIGQl to the other endof said spring and which is adapted to pass over an article located insaid saddle arn1s,'a second spring, one end of which is anchored to saidlever, said flexible element having its other end secured to the otherendflofsald second spring,

2.,In a work holding device, abase, end

standards projecting upwardly from said base and each coinprls'ingafront and a back bar secured to the base and converging 11pwardlyand'inwardly,'ea'ch leg having a vert'ical portion, said verticalportions extending in contact with one another, means securing said barstogether at said contacting portions, said bars having divergingupwardly extending portions constituting a saddle, each upwardlydiverging portion having ajser'es of horizontal pinholes, those of thebars of a standard aligning with each on; r, a pin located in sai'dholesof astandard and extendi'ngfrom oneupwardly divenging portion thereofto'the other diverging portion thereof, and means to hold anobjec't inplace,

on said pins in said saddle.
